# Marketplace and Den

The Stockmon Marketplace is the first-party discovery and orderbook experience for verified Genesis NFTs. **Den** is your owner workspace for viewing Stockmons and managing listings.

{% hint style="info" %}
**Marketplace is not Markets.** [Markets](/stockmon/markets.md) shows Vault balances and timestamped estimates. Marketplace lists and settles Genesis NFT orders without taking custody.
{% endhint %}

## Noncustodial by design

Stockmon never takes custody of a seller’s NFT, a buyer’s funds, or either user’s private key.

Marketplace settlement uses:

* wallet-authenticated users;
* user-signed orders;
* onchain ownership and approval checks;
* self-custodial buyer funding;
* a noncustodial settlement protocol; and
* reorg-aware order and receipt indexing.

The hosted orderbook helps people discover orders. It is not authoritative for ownership, approval, cancellation, or settlement—the chain is.

## Seller flow in Den

When Marketplace is available, an eligible seller reviews:

1. Stockmon and token ID;
2. listing currency and price;
3. expiration;
4. venue distribution;
5. **0.85% seller-paid Stockmon fee**;
6. estimated seller proceeds; and
7. wallet approval or signature request.

Updating or cancelling a listing must preserve its exact order identity and current onchain validity.

## Buyer flow

A buyer sees the verified art, DNA, current owner, order freshness, total price, currency, and settlement target before confirming.

If an ETH-to-USDG funding route is offered, it must remain self-custodial and separate from the NFT purchase confirmation. A failed live route must never silently fall back to simulated funds.

## First valid fill wins

Stockmon and external venues can show the same signed order. The first valid onchain fill wins; stale copies must become unavailable after indexing catches up.

{% hint style="warning" %}
An orderbook row is not proof that an NFT is still for sale. Always revalidate ownership, approval, expiration, cancellation state, and settlement status immediately before execution.
{% endhint %}

## Marketplace boundaries

The Marketplace does not authorize:

* duplicate Genesis tokens;
* custody or internal real-money balances;
* server-held user keys;
* hidden fees;
* activation of Hunt, Breeding, Feed, or redemption; or
* Aetheryn listings before the separate Aetheryn Marketplace launch.

Next: [Hunt](/stockmon/hunt.md) and [PVP — coming soon](/stockmon/hunt/pvp-coming-soon.md).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://raretyperesearch.gitbook.io/stockmon/nft-lifecycle/marketplace-and-den.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
